1. A device for orientation and position detection of markings in three-dimensional space, the device comprising:
at least one marking arrangement, the at least one marking arrangement comprising at least two marking units each having at least three illuminating means arranged along a path, the illuminating means being designed as markings and/or communication elements;
at least one optical image capture unit configured to capture images of the marking arrangement; and
an evaluation unit configured to unambiguously determine an orientation and a position of the marking arrangement from exactly one image of the at least one optical image capture unit,
wherein:
at least one of the marking units belongs to a first marking unit type having at least three markings,
at least one other of the marking units belongs to a second marking unit type having exactly two markings and at least one communication element, the at least one communication element being arranged between the two markings,
at least one of the marking units of the first marking unit type and at least one of the marking units of the second marking unit type are arranged in a non-coplanar manner, and
the evaluation unit is adapted to recognize the marking units of the first marking unit type and the second marking unit type and to unambiguously determine the orientation and the position of the marking arrangement using the markings of recognized marking units of the first marking unit type and the second marking unit type.
